IMPROVEMENT IN BUSHES FOR MILL-SPINDLES.

Specification forming part of Letters Patent No. 150,751, datcd May 12,1874; application filed March 14, 1874.

To all whom it may concern Be it known that I, EDWARD Dnnns, ofBrighton, in the county of Washington and 7 State of Iowa, have inventeda new and usethe side ribs.

Similar letters of reference indicate corresponding parts.

A is the bush, which is made of cast-iron, and set permanently in thecenter of the stone. B represents the spindle, which passes up throughthe center of the bush, as seen in the drawing. The bush is made withrecesses 0, (three ordinarily,) in which are fitted the boxing-pieces D,the faces of which bear against the spindle, and support it. Thesepieces D are made with faces hollowed out to fit the spindle. Theirbacks are beveled from the center, as seen at E in Fig. 2, thebearing-surface of the back being at the point F. On each of the sidesof these pieces is a rib, G, (see Fig. 3,) F being the bearing-point ofthe back. The ribs G are the bearing-points of the sides, which come incontact with the sides of the recesses in the bush. The pieces D canrock and readily adjust themselves to the spindle. H representsawedge-shaped piece placed. in the back of the recess, in rear of eachof the box-pieces D, against which the pieces D bear as seen in Fig. 2.I is a set-screw, which passes through the upper ends of these pieces 4H, the ends of which bear against the back of the recess, as seen at J.By turning these screws the boxes D are forced up to the spindle, whileat the same time they readily adjust themselves to the spindle. Theseboxpieces D may be made of any suitable material, and faced withbabbitt-metal, if desired. The pieces H are preferably of metal, but maybe of any suitable material.

By this arrangement it will be seen that the boxing is adjusted to thespindle-bearing in the most accurate and perfect manner, while anylooseness caused from friction and wear, is easily taken up by turningthe set-screws.

Having thus described my invention,Icla-i1n as new and desire to secureby Letters Patent The combination, with bush having cavities O, andbeveled boxes D having side ribs G, of the vertical pieces H, taperingfrom bottom to top, and at the latter point made adjustable by a screwat rightangles thereto, as set forth.
